Do pandas hibernate?

No. Unlike many bears in cold climates, giant pandas do not hibernate. Bamboo is too low in energy for a panda to build the large fat reserves hibernation requires, so it keeps eating through the winter instead. Red pandas do not hibernate either, but in severe cold they can drop into short periods of dormancy, lowering their metabolism and waking every few hours to feed.

Why most bears hibernate and pandas do not

Bears such as brown bears and American black bears fatten up on calorie rich food in late summer and autumn (nuts, berries, fish, meat) and then live off that fat through winter in a den. Hibernation is a strategy for surviving a season when food is scarce, and it only works if an animal can store enough energy beforehand.

The giant panda has neither part of that deal. Its food is bamboo, which is very low in usable energy, and a panda already has to eat for 10 to 16 hours a day just to cover its daily needs. It cannot lay down months of fat. On the other hand, bamboo stays green and available all winter in its mountain forests, so there is no seasonal famine to sleep through. The result is that a panda's best strategy is to keep eating.

How giant pandas cope with winter

• Insulation. A thick, woolly coat keeps pandas warm in cold, wet mountain forests; the Smithsonian highlights it as a key adaptation.
• A very low energy lifestyle. A 2015 study in Science found giant pandas use only about 38 percent of the daily energy expected for a mammal their size (about 45 percent in the wild), with low thyroid hormone levels and low activity. Saving energy all year reduces the need to save it in winter.
• Moving with the seasons. Pandas range over elevations from about 1,200 to 3,500 m and shift where they feed as bamboo and weather change through the year.
• Snow camouflage. One study of panda coloration argued that the white parts of the coat help pandas blend in with snow, and the dark parts with shade, precisely because a panda that never hibernates must be hidden in both winter and summer. See why are pandas black and white?

Red pandas: no hibernation, but a clever shortcut

Red pandas face the same low energy bamboo diet and have their own answer. According to the Smithsonian, in significantly cold temperatures red pandas can become dormant: they lower their metabolic rate and raise it again every few hours as they wake to look for food. This lets them spend nearly as little energy as a sloth. They also curl into a tight ball with the long bushy tail wrapped around the body to save heat. In warm weather they do the opposite, stretching out along branches and panting.

This is a form of short term torpor, not hibernation: a red panda does not disappear into a den for months, and it keeps feeding through the winter.

Do pandas sleep a lot, then?

Yes, but in short pieces rather than one long winter sleep. Wild giant pandas usually rest two to four hours at a time between feeding bouts, sometimes six or more hours in summer. Red pandas spend about 45 percent of the day awake and are most active at dawn and dusk. See panda behavior for a full daily routine.
